What is Psychrometrics the study of?

Psychrometrics is the study of atmospheric air, which is a mixture of pure air and water vapor at atmospheric pressure.

What do you mean by the term Psychrometry?

Psychrometry is the study of the thermodynamics of gas-vapor mixtures. Psychrometry is the study of the properties of moist air and is useful to engineers concerned with heating, cooling, and ventilating buildings. Psychrometry is the subject which deals with the properties of gas-vapor mixtures.

What are the important psychometric process?

a psychrometric process that involves the increase or decrease in the temperature of air without changing its humidity ratio. Example: passing moist air over a room space heater and of kiln air over the heating coils.

What is psychometric chart and explain various components involved with neat sketches?

A psychrometric chart presents physical and thermal properties of moist air in a graphical form. It can be very helpful in troubleshooting and finding solutions to greenhouse or livestock building environmental problems.

How is wet bulb temperature determined?

Wet bulb temperature is the lowest temperature to which air can be cooled by the evaporation of water into the air at a constant pressure. It is therefore measured by wrapping a wet wick around the bulb of a thermometer and the measured temperature corresponds to the wet bulb temperature.

What is Psychrometry in refrigeration?

Psychrometry is the study related to the thermodynamic properties of wet air (mixture of dry air and water vapor), such as temperature, moisture, enthalpy and specific volume.

What are the different types of psychrometric process?


  • A view of psychrometric chart is shown:
  • The different psychrometric processes are shown:
  • Sensible Cooling.
  • Sensible Heating.
  • Cooling and Dehumidification.
  • Sensible Heat Factor (SHF)
  • Heating and Humidification.
  • Cooling and Humidification.

What is Psychrometrics state its applications?

What is DBT and WBT?

Knowing both the dry-bulb temperature (DBT) and wet-bulb temperature (WBT), one can determine the relative humidity (RH) from the psychrometric chart appropriate to the air pressure.

What is the importance of psychrometric ratio?

The psychrometric ratio is an important property in the area of psychrometry, as it relates the absolute humidity and saturation humidity to the difference between the dry bulb temperature and the adiabatic saturation temperature . Mixtures of air and water vapor are the most common systems encountered in psychrometry.

What is psychrometrics?

Psychrometrics, psychrometry, and hygrometry are names for the field of engineering concerned with the physical and thermodynamic properties of gas – vapor mixtures. The term comes from the Greek psuchron ( ψυχρόν) meaning “cold” and metron ( μέτρον) meaning “means of measurement”.

What are psychrometric properties dependent on pressure?

Many psychrometric properties are dependent on pressure concept: atmospheric pressure at the location of the sample. A psychrometric chart is a graph of the thermodynamic parameters of moist air at a constant pressure, often equated to an elevation relative to sea level.
